Benefits of technology

[0016] In this way, it is possible to improve the work efficiency up to the time of obtaining the small-width webs which are cut and on which the marking patterns are formed. Further, by carrying out the marking processing before cutting the web, it is possible to accurately form the marking patterns at the appropriate positions of the web.
[0018] In accordance with the present invention, it is possible for the single marking mechanism to form the marking pattern on each of the divisional webs which have been divided by the cutting device. Accordingly, the marking mechanism does not cause the processing device for carrying out processing of the web to become large-sized.
[0025] In this way, marking patterns can be formed appropriately at predetermined positions of the web to be cut into several webs, regardless of the widths of the webs.

Problems solved by technology

This leads to the processing device becoming larger.

Embodiment Construction

[0032] Embodiments of the present invention will be described hereinafter with reference to the drawings.

[0033] FIG. 1 shows the schematic structure of a web processing device 10 applied to an embodiment of the present invention. The web processing device 10 uses an elongated X-ray film 12 as a web. A web roll, which is formed by the X-ray film 12 being wound up in roll form, is set into the device 10. In the device 10, in the process of conveying the X-ray film 12 while pulling the X-ray film 12 out from the web roll, the film 12 is cut at a predetermined position in the transverse direction which is orthogonal to the conveying direction. The respective cut X-ray films 12 are wound into rolls. Plural rolls of the X-ray film 12, whose widths are smaller than that of the web roll, are thereby formed.

[0034] The web processing device 10 may form rolls of X-ray films 12 in their final states. Or, the web processing device 10 may cut the X-ray film 12 at predetermined intervals along the...

Abstract

In a web processing device, a marking head is disposed so as to oppose an X-ray film which is trained about a print roller which is at an upstream side of slitting blades. Within a scanning range of a laser beam of a marking head, two printing regions are disposed with a non-printing region therebetween. The non-printing region is disposed so as to oppose a cutting line which is cut by the slitting blades. Before cutting the X-ray film, the web processing device forms marking patterns on both sides of the cutting line.

Description

[0001] 1. Technical Field[0002] The present invention relates to a web processing device which cuts a web into predetermined sizes. In particular, the present invention relates to a web processing method and web processing device which form marking patterns, which include visible characters, symbols, or the like, on the web to be cut along a conveying direction thereof.[0003] 2. Description of the Related Art[0004] There exists a technique for carrying out marking processing on a web by irradiating a laser beam (laser light) onto the web while continuously conveying the web. Such a technique is proposed in, for example, Japanese Patent Application Laid-Open (JP-A) No. 5-238098.[0005] Various types of conventional techniques have been proposed which are applied to a photosensitive material (such as an X-ray film) which is a web, and which form a marking pattern on the photosensitive material. For example, Japanese Patent No. 3,191,201 proposes setting the laser irradiation time (puls...
